1
Guaranteed by design.
2
Measured between VIN and SW pins—includes bond wires and pin resistance.
3
Based on bench characterization. Measured with V
IN
= 12 V, V
OUT
= 1.2 V, load = 1 A, f
SW
= 1 MHz, and the output in regulation. Measurement does not include dead time.
4
Based on bench characterization. Measured with V
IN
= 15 V, V
OUT
= 12 V, load = 1 A, f
SW
= 600 kHz, and the output in regulation. Measurement does not include dead time.
5
This threshold is expressed as a percentage of the nominal output voltage.
